I begun few weeks ago to work with MoI, am not professional in drawing 3D, but here I get really good and fast results for what I need.
And working with MoI makes a little addicted, because I can think about the thing and not how to draw it.
Often it will be enough to make a screenshot to send in a JPG, to give somebody an idea about things. Only with coloured surfaces.

Now if I do this, I have a different pixel-resolution-result as importing the things in sketchup and do the screenshot there (after material painting).
In the screenshot from Sketchup the edges are more sharpen.
